To (all whom it may concern:

Be it known that I, OBEDIAH' SMITH, of Bloomington, in the county of McLean and tate of Illinois, have invented certain Improvements in Motors, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a front view of a machine embodying my improvements. Fig. 2 is a side to View of the same. Figs. 3, 4, 5, 6, 7, 8, 9, and

are views of detached parts, to which more particularreference will be made further on.

Fig. 11 is a view of a modification.

Referring to the letters upon the drawings 15 in aid of a description in detail of my invention and a machine in which it is applied, A indicates a frame.

B indicates a series of springs secured to a cross-piece, O, bolted to the frame, as clearly shown in Fig. 2.

D is a spring-arbor corresponding to the main spring-arbor of an ordinary clock. Connected with this arbor is an ordinary clockwork or train of gears with an escapement and pendulum, such as are common, and need not be described.

All the mechanism thus far mentioned is old, and forms no part of my invention, but is referred to as an example of mechanism to which my improvel'nent is conveniently and advantageously applicable.

Referring, now, particularly to my improvement, it consists of a device for regulating motion in the manner of a balance-wheel; and it consists in certain appliances connected with a balance-wheel, or going to make an improved balance-wheel, which I will now point out.

cferring to Fig. 8, which is a detached view of my invention, E is a rim corresponding to that of an ordinary balance-wheel.

F F F F indicate shot-buckets pivoted, respectively, to the hub G, as shown. At the outer ends of these buckets are loops H, which encircle the rim, upon which are stops Z, to limit the swinging or pendulous movement of the buckets. These buckets are each provided with an inclined partition, K, as indicated in Fig. 6, and are secured to their pivot-arnis L at one side of their center. The compartment marked M in Fig. 6, being the larger in each bucket, contains metal balls.

0 indicates a disk which is secured around the axle, forming part of the hub of the wheel, and is clearly shown detached in Fig. 7. Secured to this disk upon ribs P are bent springs Q, so adjusted as to bear against the bases of the shot-buckets, as shown in Fig. 3.

Connected with the shaft R, in Fig. 2, is a crank, S, and pitman T, as clearly shown in Fig. 1. The pitman T is pivoted to a bellcrank lever, U, pivoted to the frame at V, and pivotally connected to a pitman-rod, \V, which last may be connected with a pump, a churn, a sewing-machine, or any other machine ca pable of being run by spring vmotive power. Instead of this pitman, crank, and lever mechanism, a band and pulley or gears might be employed for communicating motion to any suitable machinery.

In Fig. 10 is represented detached a springcatch, R, applied as indicated at R in Fig. 1, to hold the pendulun X in place when it is desired to stop the machine.

The operation of my improvement is as fol- 7 lows: Referring to Fig. 3, it will be perceived that when the buckets are at the farthest distance from the stops I they will compress the springs at the hub, which are of such strength as not to be quite sufficient to overcome the weight of the loaded buckets. \Vhen that portion of the revolution of the wheel is reached at which each bucket nearly approaches the perpendicular, so that part of its weight is upon one side of a. perpendicular line through 85. the center of the axle, the spring will then tip the bucket over until its loop strikes its stop, which will cause the shot within the bucket all to suddenly pass by force of gravity to the opposite side of the perpendicular line l'rom where they were prior to the action of the spring. The result is, the weight of the shot is shifted from a position tending to retard the rotation of thewheel to a position aiding its rotation. The shifting is sudden by the com- 5 bined action of the spring and gravity, and the shot falling more rapidly than the rotary movement of the wheel exerts a sudden impulse upon the bucket, which is communicated to the wheel in aid of its rotary movement. :00

It will be observed that the form of the inner end walls of the buckets is circular, so that when the metal balls are to move, as just described; to aid the motion of the wheel, they will move suddenly. The curvature of the outer or opposite ends of the buckets is, on-

mere additional weight affects such hinder ance, which is not objectionablein a balancewheel. The balls move gradually by force of gravity, except at the time when the buckets are tilted by the combined action of gravity and the springs, when the balls move suddenly and effectively, as above explained. The inclined partitions are intended to aid the effect of the falling of the balls when the spring acts, the inclination beingsuch and the adjustment of the partitions also being such as to cause the balls to run down toward the hub a little sooner than they would without the partitions; but the partitions maybe dispensed with if desired. Instead of having'a loop on each bucket to loosely clasp the rim of the wheel, a formal change might be made by having a stud working loosely in 'a curved groove in the side or body of the wheel, as shown in Fig. 11; but I prefer the form first described. Each successive bucket thus gives an impulse to the rotary movement of the wheel, and upon its shaft, equal to the inertia of the falling shot and the bucket.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is'

1. The combination of the wheel, the stops thereon, the loaded buckets loosely connected to the rim or body of the wheel and pivoted to the hub, and the springs, substantially as set forth.

2. In combination with the wheel having stops, the buckets pivoted to the hub, and limited in oscillating movement by the'stops, the bucket-springs, the. inclined bucket-partitions, and the loose balls in the buckets, substantiaily as set forth.

- 3. In combination with a wheel, the buckets pivoted to the hub, and provided with springs at the hub, and with stops at the rim, the ends of the buckets being curved, the buckets containing balls, and the curved ends serving to make the motion of the balls gradual, except at the moment of tilting the buckets by the action of the springs, substantially as set forth.

In testimony whereof I'have hereunto subscribed my name.
